METAL-SCRAP COMPRESSOR.

Specification of Letters Patent.

Application filed March 16, 1908.

Patented Nov. 15, 1910. Serial No. 421,561.

' for example as that produced by can factories, may be rapidly, conveniently and cheaply compressed into blocks or billets of 50 or 100 pounds or other desired weight and with little hand labor.

My invention consists in the means I employ to practically accomplish this object or result; that is to say it consists in a horizontally and longitudinally reciprocating cage or carriage furnished with a plurality of molds, preferably four, so that the scrap may be filled and condensed into one pair of them while it is being compressed into a I solid block in one'of the other pair, and the compressed block ejected therefrom, in combination with a compressing hammer, preferably a steam hammer, a reciprocating anvil block adapted to be moved under the compressing hammer during the compressing of the condensed scrap in each mold and to be withdrawn from under the same to permit the compressing hammer to eject the solid or compressed block of scrap from the mold, and a pair of traveling scrap condensing plungers, preferably pneumatic, for condensing the loose scrap in the mold as it is filled into the same by the workmen, one of said condensing plungers being mounted to travel on a suitable longitudinal track at each side of the compressing hammer, so that it may be easily and quickly shifted over each and both of the pair of molds being filled.

The invention further consists in the novel devices and novel combinations or parts and devices herein shown or described.

In the accompanying drawing, forming a part of this specification, Figure 1 is a side elevation, partly in longitudinal sec tion, of a scrap compressor embodying my invention; Fi 2 is a partial central vertical longitudinal section; Fig. 3 a crosssection on line 33 of Fig. 1; Fig. 4: a cross section on line 4- 1 of Fig. 1; Fig. 5 a detail side elevation of one of the traveling pneumatic scrap condensing plungers or devices; Fig. 6 a horizontal section on line 66 of Fig. 5; Fig. 7 a vertical section on line 7-7 of Fig. 6; Fig. 8 a detail vertical cross section on line 88 of Fig. 1; Fig. 9 is a detail vertical section on line 9-9 of Fig. 1; Fig. 10 a detail View, partly in section, on line 101O of Fig. 3; Fig. 11 a detail horizontal section on line 1111 of Fig. 1.

In the drawing A represents the general frame and foundation work of the apparatus, B are the molds, B the mold carriage or slide, B the track for the mold carriage or slide B C the feed plate or floor from which the tin plate or other scrap is fed into the molds B, D the steam compressing hammer, E a reciprocating anvil block adapted to be moved under the compressing hammer, E the anvil, F F the condensing plungers or devices, preferably pneumatic, one on each side of the steam hammer D, F the trucks or carriages for the condensing plungers, F the track for the traveling trucks F of the pneumatic scrap condensers F, H the bottom plate which closes the lower ends of the molds, and K the conveyer for the compressed blocks of metal scrap as the same are discharged from the molds, the movable anvil block operating to push them onto the conveyer.

The molds B are preferably four in numher, and each is preferably provided with shoulders I) for engaging the mold carriage or cage B in which the molds fit and by which they are reciprocated horizontally and in a longitudinal direction so as to bring each mold in turn under the steam compressing hammer D. The molds B are preferably made in separate pieces and each in a separate piece from the mold carriage or cage B The mold carriage or cage B is preferably of a rectangular shape in horizontal section, as illustrated in Fig. 11, and its side bars 72 are furnished with guide flanges 6 adapted to fit and reciprocate upon the stationary guide bars or rails B which constitute the track for the mold carriage or slide B The track rails or bars B are also furnished with flanges b at their lower edges.

The mold carriage or slide B is preferably reciprocated as required by a hydraulic carriage or slide B The reciprocating mold carriage or sllde B or its operating stem or rod b is provided with a registering bar or rod 6 having registering notches b which engage a movable registering pin or device If mounted on the main frame of the machine to cause the molds to be brought into proper registration with the steam hammer D, anvil E and movable anvil block E. The stop or registering device 6 is operated at intervals as required by means of a hand lever b and suitable connecting link and levers 5 12 79 and 6 on the shaft 6.

The feed plate or floor C from which the scrap is fed into the molds B is provided on each side of the compressing hammer D with feed opening C through which the scrap is feed or delivered into the molds B from both sides and from time to time condensed therein by the traveling condensing plungers or devices F. Y

The compressing hammer D is preferably a steam hammer and actuated by a steam cylinder and piston D D and provided with a controlling valve (1 and operating lever al and suitably mounted on the main frame or foundation work of the apparatus.

The reciprocating anvil block E is mounted to slide upon the anvil E so that it may be brought under or in line with the compressing plunger or han mer D so as to close the lower end of the mold in which the scrap is being compressed by said hammer D, and so that it may be withdrawn from under the mold to permit the compressing hammer to eject or discharge the compressed block from the mold. The movable anvil block E is preferably furnished with a notched or inclined face E to cause the compressed block of scrap to be properly delivered or to slide onto the conveyer K. The movable block E is preferably reciprocated as re quired by means of a hydraulic cylinder and piston E E and a rod E connecting the movable anvil block E with the piston E of the hydraulic cylinder E The scrap condensing or tamping devices or plungers F are preferably operated each by a pneumatic cylinder and piston F I the cylinder F being mounted upon the traveling carriage F which is preferably furnished with upper and lower flanged wheels f to engageabove and below the track rails F and thus hold the truck or carriage F securely in position on the track rails while permitting it to be easily and quickly pushed along the track rails to bring the condensing or tamping plunger over either one of the two or more molds B which are being simultaneously filled with the thepneumatic scrap condensing or tamping I haust of compressed air to the pneumatic cylinders F in through the compressed air supply pipes f f f f, and out through the exhaust pipes The compressed air supply pipe has a flexible section f so that the trolley or truck F may .be freely moved on the track F The valves for controlling the admission and exhaust of steam to the cylinder of the steam hammer and of water to the hydraulic cylinders which operate the mold carriage and the anvil block may be of any suitable construction, but are preferably of substantially the same construction as that above described for the pneumatic cylinder of the scrap condensing or tamping plungers.

The bottom plate H is preferably supported from the track rails B of the mold carriage by connecting rods it. This bottom plate is furnished with an opening h therein which registers with the steam hammer D and the anvil block E when said anvil block is under the steam hammer, so that when the anvil block is withdrawn the hammer D may eject the solid or compressed block of scrap K through this opening i The bottom plate H serves to close the bottom of the molds B while they are being filled, and to resist the pressure of the pneumatic condensing or tamping plungers F.

The conveyor K is preferably an endless chain conveyer, the links of which are furnishe d with arms 7'; to engage the solid or compressed blocks of .scraps X. This conveyer K receives the blocks of scrap as they are discharged upon it from the molds by operation of the steam hammer D and reciprocating anvil block E, and operates to convey the blocks X out of the pit A beneath the feed floor or plate C. The conveyer K is mounted upon sprocket wheels K and is continuously driven through suitable operating mechanism K I claim:
